Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 268 Issued at 2200Z on 25 Sep 2010
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was very low. Region 1109 (N22E27) was
classified as an Ehi group with a Beta-Gamma magnetic configuration
and produced a few B-class flares during the period. No new regions
were numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. However, there is a slight chance for an M-class flare
from Region 1109.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was at quiet to unsettled levels as a recurrent
coronal hole high-speed stream continued.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet during days one and two (26-27 September).
Quiet to unsettled levels are expected on day three (28 September)
as a weak, recurrent coronal hole high-speed stream becomes
geoeffective.
